Start Preamble July 15, 2010.

On April 19, 2010, Copper Valley Electric Association, Inc. filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act, proposing to study the feasibility of the Silver Lake Hydroelectric Project, located on Silver Lake and Duck River, in the Valdez-Cordova Census Area, Alaska. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners' express permission.

The proposed project would consist of the following: (1) A 400- to 600-foot-long, 100- to 125-foot-high roller-compacted concrete dam constructed at the outfall of Silver Lake to Duck River; (2) Silver Lake, with a surface area of 1,678 acres and a storage capacity of 165,200 acre-feet at elevation 425 feet mean sea level (msl) [1] ; (3) a 9-foot-diameter, 6,000-foot-long buried steel penstock; (4) a powerhouse containing three Francis turbine/generating units having a total installed capacity of 15 megawatts; (5) an open-channel tailrace; (6) an ecological return flow facility to support resident species within the bypassed reach of the Duck River; (7) a 50-foot-wide, 140-foot-long switchyard, with generation stepped down at the switchyard to serve local requirements; (8) approximately 4.5 miles of new roads to access the dam and powerhouse; (9) a 100-foot-long dock bulkhead with a 20-foot-wide, 30-foot-long seaplane/floatplane ramp; (10) a 300-foot-long, 150-foot-wide housing structure for plant operators; (11) a 40-foot-wide, 100-foot-long maintenance shop; and (12) appurtenant facilities. The proposed Silver Lake Hydroelectric Project would have an average annual generation of 44.8 gigawatt-hours.
